animation of wielded statue

     Fix the reported bug of problems after casting stone-to-flesh spell
on self while wielding a statue.  Pointers for worn items weren't kept in
sync and various potential symptoms could occur (most easily visible one
being that ')' falsely reported the no longer existing statue as still
wielded; report stated that one crash was observed).  This bug predates
3.4.2 and was probably present ever since stone-to-flesh got introduced.
